The pillow or bucket distortion is an inherent phenomenon of the vibration mirror marking, and the method determined by the scanning mode of the mirror is the signal correction of the distortion. There are two ways to correct the correction, one is the hardware correction, the current use of less.
The other is the software correction, this is the present I use more one;
The method of hardware correction is to change the voltage value of the analog signal of D/a card through a correction card according to certain rules, and then transmit the signal to the vibration lens; Software calibration method is to mark the software itself with a correction function, marking the process, the digital signal in accordance with a certain method of disposal penalty, and then transmitted to D/a card.
